Several drug manufacturers issued recalls for the diabetes drug Metformin because it may contain N-Nitrosodimethylamine (NDMA) -- a cancer-causing ingredient -- above the levels allowed by the U.S Food and Drug Administration. Metformin is used in the treatment of Type 2 diabetes mellitus to manage blood glucose levels.

Consumers who have the recalled medications in their possession are urged to return them to the manufacturer and contact their healthcare providers for an alternative treatment plan.

Here is a look at all the diabetes medications that have been recently recalled.
